Silicone leads for temperatures to 390°F (200°C) are most often supplied, but many other types are available. The leads are attached to the element within the transition area and covered with a patch of the same material as the sheath.

The entire lead transition assembly is then vulcanized to the heater sheath. Leads can be arranged to exit at about any point on the element sheath, corner, or from an external tab. Neoprene, silicone and Teflon leads along with SJ and HPN cord and plug sets can be supplied.

Silicone Rubber leads are standard unless otherwise specified. Teflon leads are also available. 14, 16, 20 or 24 gauges are sized by requirement. Maximum lead length is 72". Available with Patch and Strain Relief Tab.

MOUNTING METHODS

Pressure Sensitive Adhesive (PSA) is a factory applied material for bonding Flexible Heaters to a flat, smooth surface. A peel-away protective backing allows simple field installation. The maximum element temperature for PSA use is 300°F (150°C) continuous, at no more than 5 watts per square inch. Heaters with PSA should be stored no more than 6 months before installation.

Factory Vulcanizing provides excellent heat transfer from the heater element to the customer part. Strong, free of air gaps and with the longest possible heater life are advantages of Factory Vulcanizing.

For field applied adhesives, an RTV Room Temperature Vulcanizing Adhesive or Contact Cement are available. Consult Ogden.

Also available for Flexible Heaters are several mechanical field mounting devices such as hooks and laces, grommets and laces, spring loaded latches, snaps or velcro.
